Route: Tahoe Rim Trail (CA)

California, US

The Tahoe Rim Trail (TRT) is a 165-mile long loop trail around Lake Tahoe. The trail is relatively new, and its "grand opening" celebration was in September 2001. Nevertheless, the TRT has already seen several speed record attempts -- a testament to the quality of the trail as well as its location near to the hub of ultrarunning in North America. An interesting feature of the trail is that, since it is a loop, one can choose basically any starting/finishing point, and can run in either direction (clockwise or counter-clockwise). No doubt different runners will have different ideas on the most efficient approach.

Hello friends,

I will be starting on July 1st, at 8:00am PST Time, a FKT attempt unsupported on the Tahoe Rim Trail.

I will start from Spooner Summit trailhead and go counterclockwise, following the current FKT holder Sean Ranney.

My primary goal will be to try finishing the loop in less than 2.5 days, and best case improve the time from Sean of 51h45min.

My attempt can be followed at the following link:

p.s.: Blue dote on the map can be clicked to check my progress compared to Sean's time.

Looking forward to that,


Admin note:  Looks like Aurelien did not complete the route.


Following my last attempt were I got sick, I will give another try this friday july 13th starting around 4am PST time.

I have changed few things from the the last failure: no chili con carne the day before, 2 liters of water instead of 1, better clothes against the heat, less fatty food to eat on the trail.

I failed again at my second attempt on the Tahoe Rim Trail. Failing is a good learning process. I feel a lot more humbled, and impressed by Sean time more than ever. First time I quit after 63 miles in 19hours, second time I quit after 110 miles in 40hours. Here is my outcome:

- It is hard to admit, but maybe one mistake was to think I could do it, while this challenge is maybe to tough for me. Everyone should dream big, but should be ready to fail and plan accordingly. If there is a next time, I'll need to train a lot harder.

- I got sick very early on my first attempt due to heat exhaustion, and same issue on my second attempt after 60miles and 15hours. Not being able to eat and drink much did not help my body and my legs to keep the pace and to recover, even though I still dont know if this is the main issue, or if I am just too weak overall. If there is a next time, I'll go with a perfect cloudy cool weather in august or september.

Having a hard time to accept failure, but still think those experiences are a great way to learn about myself.


Is there a women's unsupported record? 

I would love to know the answer to this too!
